 - `install-stage1.sh`: sets up the base system and prepares for installation stage 2
 - `install-stage2.sh`: continues setting up things after booting into the freshly installed base system
-- `opt/grub-config`: the custom grub config generator to be installed in /opt/void-usb

-- `opt/backup-fs`: helper script to regenerate the squashfs

-- `procedure.txt`: notes to self, will disappear once finished
+  - `backup-fs`: helper script to rebuild the squashfs
-- `bootup.sh`: script that sets up the overlay
+- `kernel.d/`: kernel hooks to be installed in /etc/kernel.d
-- `bashrc`: just a custom bashrc
+- `skel/`: files to be added to /etc/skel
-- `update-squashfs.sh`: runs at shutdown, allows user to back up the system

 Steps to install:
-  - (user does this:) boot Void installer

-    -> log in as root
-    -> connect to the internet
-    -> download and run install script
-  - preparations:
-    -> update xbps
-    -> install xmirror squashfs-tools
-    -> make our own or extract (if feasible) kb selection and time zone selection to hijack them for our purposes
   - select kb layout
-  - set up disk
-    -> select disk from a list
-    -> warn user about formatting and making the USB stick unusable with Windows
-    -> allow user to double check that it’s the USB drive
-    -> wipe and partition disk (new gpt)
-      -> 2M BIOS GRUB
-      -> 268M ESP

-    -> format partitions
-      -> ESP FAT32
-      -> /boot and /container F2FS
-  - mount them things
-    -> set up plain tmpfs as / for now
   - install base system
-    -> select mirror
-      -> just use xmirror and get the result from the file
